Hi, your son sounds very much like mine. Only my boy is four and looks six. Something that has helped my son tremendously is finding that he has food triggers. Corn and soy (which are in just about everything) make him extremely hyperactive and impulsive. It is a lot of work but so worth it. I used the Whole30 program (which is an elimination diet. I was already aware that corn was an issue but on the whole 30 I learned that soy also affects him. Something to think about.
